Check all wiring for short circuits, interruptions, reverse polarity and
conductor cross-sections.
– Earth the components exactly as prescribed in the specific INDRAMAT
connection diagrams.
– Observe the valid safety precautions for the machine.
– Earth each motor to its drive module.
– Earth each drive module separately to the power supply module.
The earthable point of the power supply module is the common
reference point for all drive components.
– Connect up the common reference point of the power supply module
to the source earth.
Danger
The earth connections described above are operational earths
and have a protective function. Do not disconnect them!
– Make an electrically conductive connection between the frames of the
drive controllers and the rear wall of the cabinet (electromagnetic
compatibility)).
– Twist the power cables leading from the drive controllers to the motor
or lay a four-core cable (3x phase, 1x earth).
– Check the conductor cross-sections for compliance with VDO 0113.
Power conductors leading to additional modules or other buffers should
be twisted and kept short.
Normally, the units are installed adjacent to each other and the power
connection is made using two conductor rails. If this is not possible, use
two 16 mm
2
twisted conductors with a maximum length of 1 m.
Check that:
– proper contact has been made
– terminals are firmly connected
– sub-miniature connectors are tightly screwed down.
